Application ,filed May 22,

CnouK, a citizen of the, United States, and aji'esident of the city of New York, borough of Manhattan, in'the countyand State of New York, have invented a new and Im-- proVedRailWay-Toilet Flush, of which the 'tliong f following-is afull, clear, and exact descrip- This invention relates to a new and improved apparatus to be used on railway trains to supply a suflicient' quantity of Water for sudden cleaning purposes, and isadapted to be used in connection with my invention described and claimed in my ap; plicat'iomfiled December 3, 1910, Serial No. 595,371. p

,An object of this invention is to provide means whereby the Water can be stored in a suitable 'tankor receptaeleuntil it is desired-to use the same, when the air pressure from thetrainpipesystem can be utilized to engender the necessary pressure to force tho .Watenout with asudden gush, necessary prov'ide'a flushtank with a'valve for con trolling the inlet for the air andthe outlet,

'. for the tank, whereuy whenthe'tank becomes=-.-i'-ul1- of water the water cannot pass over; into the air-pipe, and; further, when theqftankbecomes 'empty;-of;-water, the air 1 cannot pass out into-the'outletfpipe.

These and furtherobjects, together-gwit-h the constructiQnjand,pombination of parts, will be j noi'efull described hereinafter and particularly set orth in'the-claims.

'- Reference is to be'hadfto theaccompanyingdrawings forming part of this specification, in which similar characters of reff erence :indioate corresponding parts in both wFigure' l'is a vertical section through a train, with parts broken away to show the underlying'structure; and'Fig. 2 is a horis.

. Referring :more-particularly'to the separate parts-of this invention as embodied in f the form shown in the drawings, 1- indi-v cates the floor of a railroad ca'r,-inwhich is located a hopper 2, which may be of any suitable character, but preferablygis of the type disclosed and claimed in myoo pending application, above mentioned.

.Serial No. 628,678.

I For the purpose of storing water to flush the hopper 2, there is provided a tank-3, which is connectedito the hopper by means .;:.of a pipe 4', the outlet for the' tank 3- being ;iocated' at 5,'at which avalve seat 6 is proyide'd, for a purpose-tobedescribed; The tankB is preferably provided with a plurality ofspaced partitions 7-, whereby the force of Water, in passing to and fro in the tank, due'to vthe'janringof the car in running over the road, will be broken up and -:minimized.. These b'afile partitions will also haye the further use of stirring up the Water and mixing therewith any-antiseptic solu- ,tion or material which maybe placed in'the tank; The height of water in the tank may lie-indicated, if desired, by a water-glass 8, connected to the tank and having communi eating openings therewith adjacent the top and bottom. Y

pressure necessary to force out the water .into the tank, lnfiushing the hopper 2, is

at 9, through the intermediary of a pipe 10,

.itmhe described.-.Air pass'ingto. the pipe 10 avalve' l2, and also by a pressure regulator 13, which may belof any suitable character;

be ascertained byrnean's of a pressure gage 14;

pip'e 10, and extending below the same,- there may be provided moisture collector or trap 15, which will. prevent anymoi'sture in'the pipe 10, either collecting fromthe air or coming over froth-the tank-'3", from passinginto. thetr'ain-pipe 9. The water can be supplied .to -thetank 3 means of "'a pipe which-"is provided at its lower end with-a joint 17-, whereby a 'su'pplypipe source. In passing, it may ,be noted that the .pipes 10 and 16' may pass up'betw'een the partitions of the wall of the car, so'as' to be concealed from view.

necessary to" perinit the air having collected "there is provided a pet-cock, indicated at 18,

which maybe manipula'ted as desired. In

The tank is preferably air tight, and the fwhich -lets into the tank, 3' at a point 11,. yjvhere is located a'valve seat 'for a purpose The pressure beyond-the regulator 13 may.

{obtained from the air train-pipe, indicated and thus tothe tank 3 may be controlled by can readily be. attached thereto. and." water J supplied to the tank from 'anysuitable" In supplying the water, te'thtr tank,,'i't is I the train-pipe 9, there is provided a valve 19, which in this instance is shown in the form of a float-valve, which will engage the seat 1] and shut oil communication between the tank 3 and the air-pipe 10, when the water in the tank 8 comes up to a sufficient level. The valve 19 also is utilized to engage the valve-seat 6 when the water in the tank 3 reaches a low level, so as to prevent the air from the train-pipe 9 and the airpipe 10 from blowing out through the outlet or flushing pipe 4:. I I I In order to form guides for the float valve 19 and keep it in proper alinement with the seats 6 and 11, there may be provided a plurality of vertically-extending rods 20, which- 19 on several sides to move in a predetermined engage the fioat valve and constrain it vertical path;

For the purpose of having access to the interior of the tank 3, so as to' clean the same or to adjust the valve 19, in case of its becoming out of order, thereis provided a hand-hole 21, which is closed by a cover 22, having a rubber gasket 23, and secured in position by a hand-wheel nut 24, engaging a screw-threaded bolt 25 on the cover 22, and abutting against an arched brace 26, which engages the tank on opposite sides of the hand-hole 2-1. This hand-hole 21 may be somewhat elliptical in shape, so that the cover can be removed from the interior of the tank without any trouble.

The operation of the device will be readily I understood when taken in connection with the above description. Before starting on a the tank 3 at the top,

run, a hose or other connection from a source of water supply is connected at the joint 17 to the water-pipe 16 and the pet-cock 18 opened, so that the water can flow into the tank 3 and displace the air therein. When the level in the tank reaches a suflicient height, the float valve 19 will press against thevalve-seat 11, shutting off communication between the tank 3 andthe air-pipe 10, so that no water can pass over into the pipe 10 and the train-pipe 9. The level of the tank may be ascertained by the gage 8, and further supply cut ofi when enough is in the tan When it -is desired to use the system, a valve 27 in the outlet or flush pipe 4, is opened, and the air from the train-pipe 9 coming through the regulator 13 will enter and force the desired quantity of water into the hopper2.' The valve 27 may be automatic in its action, permitting a"predetermined quantity of water to pass through the flush pipe l at each operation, .or it may be desired to' have it so that it is to be manually thrown off after the claim as new through an excessive use of the water in the tank, ll of the water should become used up before the end of the trip, the valve 19 will fall onto the seat 6, preventing the air from the train-pipe and the pipe LO-t'rom passing out through the flush pipe 4. If the valve should become deranged, or it would be desired to clean the interior of the flank, access may be had thereto through the hand-hole 21, by removing the cover 22.

While I have shown one embodiment of my invention, 1 .do not wish to be limited to the specific details thereof, but desire to be protected in various changes, alterations and modifications which may come within the scope of the appended claims.

Having thus described my invention, I

and desire to secure by Letters Patent 2- 1. The combination with a sealed flushtank, of an outlet for said flush-tank, a water inlet for said'fiush-tank for filling the same, an air inlet for said flush-tank, for expelling water in said fiush tank through said outlet, and a floating valve for oscillating between said air inlet and said outlet, for controlling saidoutlet and said inlet.

2. Ithe combination with a flushing tank,

of a water-inlet at the top of said tank for supplying water to the same, an outlet at the bottom of the tank for taking the water from the same, an air-inlet at the top of the tank for supplying air to said flushing tank for forcing the water out through said outlet, and a valve floating on the water cutting ofi communication between said tank and said outlet when the tank is emptied of the water, so as to prevent air in said tank from passing into said outlet, said valve closing said air inlet when the tank is filled with water.
